To all whom it may concern:

Be it known that I, JAMES HOGAN, of Gen tralia, in the county ofColumbia and State of Pennsylvania, acitizen ofthe United States, have invented certain new and useful Improvements in Railroad Chairs and Plates, of'which the following is a specification." r l The present invention contemplates a construction for joining adjacent ends of rails and includes web engaging plates so fastened as to permit movement of the parts resulting from expansion and contraction.

Other objects of thisinvention include, with the above arrangement, means forele vating the wheels of cars above the oint to prevent thenoise resulting from engagement therewith; the provision of guide means forengagement with the wheel to prevent lateral movement; the use of a pro ection on one of the clamping plates for spacing the ties and the provision of tie plates arranged with perforations for the reception of the fasteners so spaced as to co-operate with the clamping members. p

The above objects are carried out by pro viding the clamping plates with elongated registering openings which correspond to openings in the adjacent ends of rails for the reception of bolts, the elongated openings permitting the movement of the bolts and. consequent movement of the rail ends under. expansion and contraction.

Numerous other novel features will appear by reference to the accompanying drawings forming a part of this specification and wherein like numerals, of reference designate corresponding parts throughout the several views in which Figure 1 is, a top plan view: Figure 2 is a side elevation: Figure 3 is an end view:

Figure 1 is a section on line 47-41 of Figure 1, and

Figure 5 is a perspective View of the tie plate.

Referring now more in detail to the drawings, the ends of adjacent rail sections are illustrated by reference characters 1 and 2, and are shown secured together by means of the present invention including the outer clamping plate 3 and the inner plate 4. Both of these plates are formed with elongated bolt s1ots5 through which the bolts 6 pass and are held by the usual nuts and Washers 7.

The outer plate 3 projects inwardly to snugly engage the web of the rail ends and is formed with the curved tread portion 8, the central portion of which is arched above wardly toward the rail'ends, the taper diminishing gradually from; the center and terminating at approximately the extremi located 'over the ties, and. downwardly from this flange 10 is the integral tie spacing block 12, which is located betweenthe ties to prevent lateral 'movement of the latter.

Theinner plate 4 is formedwith the web engaging portion 14 which corresponds to the web engaging portion of the outer plate.

To prevent engagement with the wheel flanges the inner plate is groovedas at 15,

and the ends of this groove merge into the curved cutaway portions 16 and 16 thus avoiding contact with the moving wheels. A

flange 17 projects fromfthe lower edgeof the inner plate and notches .18 corresponding to the notches 11 on the plat'e3are provided. 1 V

For changing the pitch of the rails a'ndwto provide. adjustable seating means, thejtie' plates 19 are utilized. These plates 19 gradually increase in thickness to form a wedge shaped body, shown more clearly in Figure 5, and are provided with spaced openings for the reception of the rail retainingspikes 21. It will be seen that the arrangement of these spike openings is such as to cause the spikes to engage the end wallsof the notches formed in the flanges of the inner and outer.

plates and this arrangement limits lateral movement of the various parts.

To provide means for the spacing of the rail ends, in assembling the present device, a transverse opening 22 is formedin the outer late 3. This opening may be of any desire shape and is located at the center of 1 the plate "so as to properly position the 1 60 the'tread surface of the rails; This tread portion 8 of the outer. plate 3 also tapers in-.

joint. In use, a suitable tool, of the desired thickness is inserted in this opening-to: proj ect between the rail ends and is withdrawn when the rails are properly locked in adjusted position.

From the foregoing it will be obviousithat the present invention provides means not only for the expansion, and contraction of the rail ends but also forms a noiseless crossing including guide means for thepassing wheels. Also, by the particular construc-v tions and arrangement of the tie plates and thev co-operating notches in the flanges an unusually firm and immovable joint is provided, all parts being secured with relation to one another without interference with the freedom of movement of the rail ends as heretofore mentioned.

What I claim as new and .useful and desire to secure by Letters Patent is 2-- 1. A rail joint comprising in combination with the adjacent ends of rails having transverse openings, inner and outer clamping plates, one of said plates being formed with an elevated tread portion, a wheel guide carried by the plate, and tie spacing means.

2. A rail jointincluding in combination with adjacent. rail ends having transverse openings, clamping plates formed with elongated bolt slots registering with said transverse openings, bolts proj ecting through the bolt slots and said openings, one of said plates being formed with a tapering tread portion, a guide flange adjacent said tread portion, and a guide groove carried-by the other plate.

3. A rail joint includingthe adjacent ends of rails, plates clamped to said rail ends, a gradually elevated tread portion carried by one of said plates, a guide flange adjacent the tread portion tapering inwardly from its respective ends to a point approximately the apex of said tread portion, and a transverse opening formed in one of the plates to permit spacing ofsaid rail ends.

4. A rail joint including a pair of clamping plates, one of said plates being formed with a curved tread portion, a guide flange adjacent. said tread portion having taper 111g; ex remi i s, th e flan e. feizfilediwith spaced elongated notches, a spacing block formed integral with said plate and projecting'" downwarelyat a point proximately. its center, and a guide groove formed in the other plate for engagement 5.
